Objective 1.1. To provide clear, evidence-based guidelines for real-time chemical characterization of fine atmospheric aerosols.
Objective 1.2. To recommend desirable features of instrumentation for the determination of real-time chemical characterization of fine atmospheric aerosols.
Objective 1.3. To optimize calibration protocols and promote best-practices for quality check procedures.
Objective 1.4. To coordinate and reinforce the exchange of scientific research necessary for understanding the factors influencing fine atmospheric aerosols.
Objective 1.5. To provide rigorous training to efficiently measure and interpret the real-time chemical composition of fine atmospheric aerosols.

Task 1.1. Training schools (two) on the use of the instrumentation to measure the chemical composition of fine aerosols in real time. They can be carried out during year 1 and year 3.

Task 1.2.  Intercomparison exercise of similar instruments (ACSM). As for the first one performed within ACTRIS, approx. 15 instruments will be compared. Depending on the outcome of the first exercise, a second or even a third intercomparison may be required.

Task 1.3. (in combination with Task 1.2) Intercomparison exercise with a large set of co-located instruments determining on-line and off-line chemical and physical aerosol parameters, which will be used to validate the on-line chemical composition of fine aerosol determined by ACSM.

Milestone 1.1. Workshop. The aim will be to share relevant scientific and technical expertise and discuss outcomes of Tasks 1.1, 1.2 and 1.3. It will allow the exchange and transfer of technical expertise between participants. It will determine if and when additional intercomparison excercises are required.

Deliverable 1.1. Guidelines for comparison of ACSM data with external data, such as Scanning Mobility Particle Sizer (SMPS), on-line instrumentation for inorganic ions concentrations measurements, or off-line chemical composition data. These guidelines may include specific procedures to be directly implemented in the software used for ACSM measurements.

Deliverable 1.2. Guidelines for real-time chemical characterization of fine atmospheric aerosols (standard operating procedure) and ACSM calibration, as output of the intercomparison exercises and experience gained during the course of the Action.
